Not all of the techniques mentioned above are Aikido techniques. I'm a shotokan practioner and let me tell you don't judge Aikido by the way it looks soft. It's very effective, it has the longest wartime history than any other martial art. You don't need not fancy spin kick and excessively powerful moves to control and opponent or win a fight. The art of throwing alone can injure or even kill a person. (Depending on how hard they land)
